HUB.

SPECIFICATION forming part of Vl'.et1:ers Patent No. 235,630, dated December 21, 1880.

Application :tiled April 19, 1879.

To all fwhom it may concern:

Be it known that I, GHAUNCEY H. GUARD, of Dayton, in t-he county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Vehicle-Hubs; and I do hereby declare the following to be a full, clear, and exact description ofthe same.

My invention has for its object an improvenient in wooden hubs for vehicles.

This improved hub consists, essentially, of a wooden core or body with an integral raised central portion, to be mortised for the reception ofthe spoke-tenons. Against the end of the raised portion and upon the core are iitted strengthening-hands. of metal and vulcanized iiber, which not only prevent the splitting ofthe hub, but also bind upon the edges oi' the central portion and securely hold its bers, so that they cannot rise by swelling under the action oi' moisture, and thus impair the symmetry and strength of thehub.

The novelty of my invention consists iu the construction, combination, and arrangement of the parts of which my improved hub is formed, as will be herein set forth and speci- `tically claimed.

In the accompanying drawings, Figure l is an axial section of my improved hub. Fig. 2 is a like view of the same with modifications.

A represents a Wooden core, forming the body of the hub, and having its ends turned in a lathe so as to form shoulders, as seen, and leave a centralportion, B, raised, into which the spoke-tenons are to be mortised in the usual way.

To strengthen this body and render the hub symmetrical, I lirst slip upon each end of the hub, up against the raised portion B, rings of sheet metal orsoft iron, O, which project up above the surface of the portion B, as seen at a, Fig. l. I next slip over each end ofthe hub a ring of vulcanized fiber or prepared paper, D, Whose inner end' is brought to bear against the inet-al ring O, as shown. These latter rings are glued, cemented, or otherwise securely fastened to the Wood which they embrace, and are so shaped as to give symmetry and proper form to the huh. By means ,of dies or other proper tools I now bend down the projecting ends ot` the rings upon the portion A, as seen at b, Fig. l, and for-ce them into the Wood, so that the top surfaces of the Wood and metal are flush.

The advantages ot' this construction are threefold First, the vulcanized liber or prepared paper band, in addition to its ofiice as a strengthching-band capable of receiving a lhigh external finish, serves as a stay to hold the metal band in place, and prevents its being crowded oli' when the spokes are driven in.

Second, the metal baud aids the paper in binding the huh to prevent splitting.

Third, the metal band, by heilig turned down. is made to cover the end fibers of the raised portion B, and so prevents its swelling by moisture, thus rendering the whole neat, compact, and strong.

Instead ot' making the metal band ot' soft metal to be turned over upon the Wood, as represented in Fig. l, it may be made somewhat thicker, as at E, Fig. 2, and have a beveled tongue, c, which, when the band is placedy up against the shoulder of the portion B, tits over a coincident chamfer upon the edge ot' said portion B. This band is Vheld from displacement by the paper band D, as in the former case, and the beveled tongue performs the office ot' the turned-over band C.

Having thus described myinventioh, I claim as follows:

In a vehicle-h ub, the combination of au inner strengthening metal baud and an outer retaining nishing-paper` or vulcanized fiber band, substantially as and for the purpose specified.

Witness my hand this 6th day of March, A. D. 1879.
